The basic premise of my work is that precision measurements of fundamental quantities can help to address the great challenges faced by physicists now – for example, how we can find and verify a theory beyond the standard model of particle physics that might eventually unify gravity and quantum mechanics. While the energy scale of such theories is typically beyond the reach of experiments, it is possible to probe for suppressed effects at attainable energies in experiments of outstanding precision. Precision measurements have played a central role in the paradigm shifts of twentieth-century physics, and I am convinced that this will continue to be the case.

My work uses methods from atomic, molecular, and optical physics. It is centered on advancing the experimental technology to push the sensitivity of experiments to new levels, and to perform precision measurements of fundamental quantities. Some examples follow. I also work on the theory required for or underlying this work.
